    摘要: The present disclosure provides an electromagnetic imaging device for an active microwave and millimeter wave security inspection apparatus, including: a two-dimensional multiple-input multiple-output array panel including at least one sub-array, wherein each sub-array includes a plurality of transmitting antennas arranged linearly and a plurality of receiving antennas arranged linearly, the plurality of transmitting antennas arranged linearly being intersected with the plurality of receiving antennas arranged linearly; a signal processing device; a display device; and a ranging radar. In each sub-array, a midpoint of a connection line between each transmitting antenna and a corresponding receiving antenna serves as a virtual equivalent phase center of a pair of the each transmitting antenna and the corresponding receiving antenna, and the plurality of transmitting antennas and the plurality of receiving antennas are arranged to generate an equivalent phase center web. A distance between adjacent transmitting antennas or a distance between adjacent receiving antennas is equal to a wavelength of the electromagnetic wave with the specific frequency, and a distance between adjacent equivalent phase centers in the equivalent phase center web generated ranges from 30% to 70% of the wavelength of the electromagnetic wave with the specific frequency.
